TRIMMER, AND FOLD.

Application filed August 2, 1828. Serial No. 655,889.

To all whom it may concern:

' ,Be it-known that I, PALACE BUTLER, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented new and useful Improvements in Wall-Paper PastersTrimmers, and Folders, of which the following is a specification. Theobject of this invention is to provide a machine for applying paste tothe proper surface of wall paper, trimming one or both edges of thepaper and folding and pilin it like it is usuall folded and piled W enpasted by hand or the operation of applying the pasted paper to a wallor ceiling.

A further object of the invention is to provide a machine capable ofadjustment to paste and trim wall paper of varying widths fed into themachine from a roll, and to produce such a machine 11y porta le that itmay be easily carried from place to place wherever the handling of paperis to be carried on; that will not wrinkle, tear or crease the aperorsmear paste upon the face or gured surface thereof.

I accomplish the above and many other minor objects which willhereinafter appear, by the mechanism illustrated in the accompanyingdrawings, in which- Fig. 1, is an elevationof that side of the machinefrom which the pasted and trimmed paper discharges.- Fig. 2, is anelevation of the crank-end of the machine, showing in dotted lines howthe front section of the folded paper table may be folded upwardly andbackwardly for the purpose of compacting the machine when it is to becarried around. Fig. 3, is an elevation looking at the opposite end fromthat shown in Fig. 2. Fig. 4 is a top plan view. Fig. 5, is a crosssection of all but the legs, on the line 5- 5 of Fig. 4. Fig. 6, is adetail in perspective of a ortion of the table-track on which the pastedpaper is folded and stacked, showing a hinged and folding end of saidtrack. Fig. 7 is a side elevation of the plate that guides the universalshaft for moving the folding table. Fig. 8, is a convenient handling inthat is simple, conven ient, com act, durable, efficient, and soreadperspective view of the scraper for removing paste excess, thethickness of the blade belng exaggerated to more clearly show itscorrugations, and Fig. 9 is a perspective view of the device formeasurln the lengths of strips to be .cut oil.

Like characters of reference indicate like parts in the several views ofthe drawings.

relatively fixed base or table 10 supports the operative mechanism of myinvention and for convenience the table is supported upon four foldinglegs 11. These are crossed in pairs as shownand the legs-of each pairare pivoted together at their intersections. They are held in crossedrelation to each other by; two-bar brace 12.v The outer ends of the barsare ivoted to the respective legs .and their inner ends are lapped andalso pivoted together. A stop 13 on' one allows the bars to break in onedirection only. (See Figs. 2 and 3.) I

The legs of each pair, sloping in the same direction, are connected b atwo-piece bar 14, pivoted together at 15. A stop 16 on one allows thebars to break only'in an upward direction for folding, and in use,thisispre vented by a diagonal brace 17 attached at one end to pivot 15,and havinga hook-slot at the other to hook over a pin 18 in one of thelegs. By releasing the brace bars the bars and legs may be compactlyfolded for carrying from place to place.

Fixed to the top of table 10, are four standards 19, that support apaste-holding box 20, here shown as the segment of a 'cylin In its ends21 oblique grooves 22 are formed to receive the end trunnions 23 of acylinder 24. The lower portion of the cylinder is submerged in the pasteand its function, when rotated, is to carry an excess of paste up andapply it to the wall paper. The grooves 22 allow for the easy removal ofthe cylinder whenit and the interior of the paste-box are to be cleaned.The box 20 has a clean out opening closed while the machine is in use,by a screw-cap 25.

Closing the grooves 22, are angle-bars 26, retained by pins 27, one-ofwhich has a wing-nut 28, the removal of which allows the bars to belifted off for cleansing purposes. MW

- member connecting whole, longitudinally the The vertical flanges ofbars 26 support a rod 29,"'-on which a U-sha ed frame swings. e e stemsof the frame parts which pass through a is in two-lapped 30, and. areheld by a setpair of 100 s 30, screw 31. justed in width to receiverolls of wall paper of different dimensions between the stems. The stemsof the U-shaped frame support a rod 32 on which the roll '33 of wallpaper is mounted. The frame is adjustable as a the rod, a screw-t readedportion 34 of which, (see Fig. 4) passes through a nut 35 fixed to theame. The rod 29 is rotated by a hand-wheel 36. A bar 37, much longerthan the stems of the frame, is fixed to one of the stems to even the paer against, so the paper will feed througi the machine properly. Thei'ollof paper bears by gravity against the paste suppl mg cylinder 24,paper' being unrolle and threaded through the machine as shown in Fig.5. It passes from the cylinder 24 to and over a roller 38, mounted onashaft 39, the bearings for which are held closed and are re.- leased bthe angle-bars 26. On an extended endof aft 39 IS a hand-crank 40, bywhich power is manually applied to operate the machine. The shaft 39 'isthe master shaft from which all of the other operative parts are driven.A sprocket-wheel 41 on 39 is connected by a link-belt with a largerwheel 42 on a trunnion of cylinder 24.

Su ported by suitable standards that are attac ed to the angle-bars 26,is a bar 43, here shown approximately ovoid in cross section, to thetapering side of which the ends of apair of strap springs 44 arefastened. These pass under and around the bar and terminate above theroller 38 with bifurcations in which circular cutters 45 are rotatablymounted.

bolt 46 from the secured end of each spring 44, passes through thespring-body above it to a rocking cam 47, an by proper manipulation ofthe cam the spring may be released to raise the cutters away from thewall paper or compressed to bring them into cutting contact. The cuttersare adjustable longitudinally of the bar 43 on the latter by releasingtheir cams which loosens the spring so they can be slid to desiredposition on the bar. This adjustment is to cut the edges of the wallpaper at the right places.

The above described cam-adjustment of the cutters provides means forreleasing one of the cutters when it is not desired to cut the edge ofthepaper on that side of the roll. The cams also afford individualcutting adjustment, but the principal cutting pressure is secured by anarm 85 hinged to the end of bar 43 to rock it, which arm is held to agiven position of the cutters by allows the frame to be ad-- of rod 29by rotating.

' its greater shaft paper from adhering ma am an engagement with atoothed-rack 86, on

the end of the paste-box.

Additional cutters may is desired to trim the margins and also to cutthe piece into narrower strips, at one operation.

The members 48, of the standards, supporting bar 43 are turved obliquelyand so positioned 5, as to' properly support the trunnions of a roller49 bearing by gravity against the printed face of the wall paper passingover the roller 38. The face of the roller may be plain, but it willpreferably be corrugated spirally as shown in Fig. 1,. to even the pasteon the pasted side of the wall paper passing between the roller 49andthe roller 38, and more particularly, to feed the paper through themachine. On the end of the shaft 39 opposite the hand crank 40, ismounted a spur gear 51 having a diameter approximating that of theroller 38. The roller 49 has a spurgear 50 mounted on end to mesh withthe gear 51 and of a diameter considerably lessthan that of the gear 51,such that in turning the roller 38, the roller 49 is thereby ositivelydriven through the ears 51 and 50 at a speed than t 1e speed of theroller 38. A scraper 52 is attached to the edge of the paste-box belowroller 39 to remove all excess of paste from the latter; but to leave a.desired minimum on roller 39, I provide a series of corrugations orgrooves 53 in the contacting edge of the scraper, but these may beomitted. Metal clips 54 of S-shape be used where it' as shown in Figs.1, 2, 3 and the paste excess removed by the scraper.

olded The pasted paper'has now to be and stacked for convenient handlingby the paper hanger, and to accomplish this I allow it to drop fromroller 39 upon a platform 55 below, having a reciprocating travel, andto kee the pasted side of the to the side of the passes, I form the ribs56' (see Fig. 1) on the side of the box.

The platform 55 has underside battens 56 with plates 57- attached totheir undersides and pro'ectin outwardly and laterally.

The plates side on metal tracks 58, having flanges 59 turned over theextended edges of plates 57 to prevent derailing of the platform.

Supported by a hanger 60 from the middle of the track is a rack-bar 61with cylindrical teeth which are engaged by a pinion 62 mounted on theend of a shaft 63 which is connected by a universal joint 64 (seeFig. 1) with a stationary shaft 65 bearpaste-box as it ing asprocket-wheel 66 that is driven by a -belt 67 from shaft 39.

By the-above construction the shaft 63 and its pinion 62 have freedom ofmovement that ermits the one side the rack to the other "when it reachesan end of the rack, and thereby reverse the direction of travel of therack and consequently of the paper folding platform to which it isattached. Movement of shaft 63 is limited by. a suitable cam-opening 68in a fixed plate 69, and the return of the table by the pinion passingaround the ends of the rack is insured by suitable stops, such astheblock 70 at one end and a bar or finger 71 at the other which fingercona wheel 76 on the master tacts with the downwardly bent end of aplate 72. The'plate 72 is pivoted to the platform and its bent endprojects down through a curved slot in the table which slot is longenough to allow the plate and its bent end to swing out of the ath offinger 71, when removal of the plat orm from the machine is desired.

It is necessary often to change the position of the platform relative tothe pasted paper coming to it, and this is accomplished by disengaging adog 74, carried 'bythe shaft 39, from a toothed-wheel 75 on the hub'of srocket-wheel 76. When the dog is out o engagement with wheel 75, theplatform drive mechanism is released, and

- the platform can be moved to any required position and connected upagain by re engaging the dog.

or very wide paper the platform is widened by plate extensions 90,having clamp plates 91 to engage the edge of the platform.

The track for the support of the reciprocating platform is made longerthan the width of the paste-box above, by hinged bracket extensions 92.These have lower diagonal brace members 93 which, with the track portionabove, are hinged to the ends of the main tracks and fixed brackets 94,by vertical pins 95. The hinge openings through members 93 are slottedlongitudinally for a swinging movement of the bracket vertically to seatand unseat a locking-lug of the end of the brace, in a hole in bracket94. The .above construction permits ofthe folding of brackets 92.

I have next to describe a means for measuring the lengths of wall paperstrips, and for stopping the machine when the length it has been set foris measured.

A shaft 78 has a loose wheel 79 driven by a worm on a shaft 80, on which*is a sprocket-wheel that is driven by a link belt 81 from a Wheel onthe shaft 39. The wheel 79 has a radially notched hub 81 with a notch ofwhich a dog pivoted to shaft 78, is engaged.

pinion to pass fromunrolled paper passes A horizontal arm 83, of the doacts in the dual capacity of a pointer and also as a stop, with adial-ring 84 fixed concentrically of shaft 78. The upper face of thedial-ring issuitably graduated, as in feet, and an adjustable stop 85 isfixed to it with which the arm 93 contacts and locks the machine whenthe arm reaches the stop. The operator then cuts off the pasted andtrimmed strip with his shears, raises the arm until it passes the stopin the further operation of the machine, and dropping the arm again tohorizontal position, continues the pasting v and trimming of anotherstrip.

lVhile I have illustrated and described my invention with. more or lessminuteness, it is capable of many modifications without departing fromthe spirit of the invention, and I therefore do not desire to be heldstrictly to the construction shown and described nor any more than isrequired by the appended claims.
